Draft 2.2

• For consistency, all functions that have cases for -0 also have cases for 0. This includes sqrt(), sin(), tan(), asin(), and atan().

• hypot()'s arguments are named $numbers for consistency.

Draft 2.1

• atan2()'s arguments must all have compatible units, or all be unitless.

Draft 2

• Variables

  • $e and $pi have 1 more digit of precision after the decimal.
  • Variables from built-in modules cannot be modified.

• Infinity and -Infinity:

  • If any argument to hypot() equals -Infinity, it returns Infinity.
  • The $exponent == Infinity case in pow() also holds for $exponent == -Infinity.
  • The $number == Infinity cases in cos(), sin(), and tan() also hold for $number == -Infinity.

• Input units:

  • clamp()'s arguments must all have compatible units, or all be unitless.
  • log() does not error unless the input has units, and instead delegates edge cases to division.

• Output units:

  • For acos(), asin(), and atan(), and atan2(), all of their outputs are numbers in deg.

Draft 1.1

• Added Background and Summary sections.
